IBEATER i R MIXER.

Application led October 5, 1925. SerialiNo. 60,491.

` My invention relates to improvementsin beater's or mixers adapted forbeating eggs or mixing different materials.

One of the objects of my vinvention is to provide a beater or mixer ofthe kind described, which is simple, cheap, durable, not i Fig. 8 is across section on the line 3-3 of Fig. 1.

Similar reference characters designate, similar parts in the differentviews.

1 designates a bearing means comprising preferably a casting having atitsupper' end a `handheld 2, and having below `the handhold a lateralrecess 3 in which is revolubly mounted a` pinion 4 which is rigidlysecured to and rotatable with a longitudinal supporting membercomprising a rod 5 which is rotatably mounted in the bearing member 1and which extends across therecess 3.

`6 designates a supporting member comp prising preferably a tuberotatably mounted in the bearing member 1 and having the` same axis asthe rod`5, the latter being extended through the tube 6 and beingrotatably mountedon and attached to a supporting button 7,`which isadapted to rest on the bottom of a container, not shown, which containsthe material to be beaten or mixed.

Rotatably mounted on the bearing member 1 is a driving gear wheel 8having an operating crank 9 and meshing with the pinion 4.

A pinion 10 is secured on and rotatable with the tube 6 and meshes .withthe teeth of the gear wheel 8 at a point diametrically opposite to thepinion 1, whereby, when the' gear wheel 8 is rotated by means of thecrank: `9, the rod 5 and tube 6 will be simultaneously revolved on thesame axis in opposite directions. f

section on the line The bearing mediate of the which is secured ontheupper end of the tube 6, whereby the latter is held from verticalmovement in themember 1.

The beater or mixer is provided with two mixing devices, each comprisinga wire helix in the form of an annulus. Secured to one helix 12 areupwardly extending supporting arms 13 which are fastened tothe rod5'below the tube 6.v Theother helix 14 is outside of and conmember 1 isdisposed interdisposed adjacent to and in the same plane as the-helix12, and hasl fastened to it and revoluble with it upwardly extendingsupporting arms 15 whichv are fastened to and revolve with the tube 6.

- In the operation of the beater or mixer, the button 7 is mounted inthe container which holds the materials'to be beaten orI mixed, andv thedriving gear is rotated by means of its crank 9, thereby revolving the'helices12'and 111 simultaneously in opposite direct-ions by means ofthe pinions i and 10,v

and rod 5v and tube 6L lBy having the arms 13 'and 15 fastened .to theupper'`r sides of the helices-12 and 14,

andex'tending therefrom obliquely upwardly to and respectively fastenedto the rod 5 and tube 6, clear spacesare-aiforded in the smaller helixand between the helices for the passage therethrough of the materialwhich is` being beaten, thereby assisting in the cir-` culation andquick mixing thereof.

I do not limit myinvention'to the structure shown and described, as manymodifcations, within the scope of the appended lclaim,'may be madewithout departing from the spirit of my invention. What I claim is In abeater or mixer of the kind described, i

two rotary members one revoluble around the other, means forsimultaneously rotatingA said members in opposite directions, twoconcentric annular wire helices adjacent to each other,l and armsrespectively attached to said 4helices and extending obliquely upwardlyfrom the tops of to and respectivelyfastened to said rotary members.

In testimony whereof I have signed my name to this specification. f
